Potassium hydroxide

Potassium hydroxide (CAS 1310-58-3 ), also known as potash lye and sold under the designation E525 in food applications, is a strong inorganic alkali used across industrial, agricultural, and food-grade processes. KOH functions primarily as a pH regulator, saponification agent, and chemical intermediate in manufacturing chains where sodium-based alternatives are unsuitable for the specific chemical reaction required. In soap and detergent manufacturing, KOH is the preferred alkali for producing soft and liquid soaps, where its potassium salt chemistry delivers the required texture and solubility profile for high-end products. Food processors use it as an approved acidity regulator in cocoa treatment, noodle production, and certain confectionery applications. Fertilizer producers rely on KOH as a potassium source in liquid nutrient formulations. In pulp and paper, it supports fiber processing and bleaching operations, while water treatment facilities use it to correct pH and prevent pipe corrosion in distribution systems to ensure safety and longevity. Potassium hydroxide is supplied as white flakes, pellets, or as a 45–50% aqueous solution. Standard grades include technical, food-grade ( FCC ), and pharmaceutical grades such as USP , BP , and Ph. Eur. These grades cover the full range of industrial and regulated applications. Bulk quantities are available in drums, IBCs, and tanker deliveries depending on the physical form and volume requirements selected. Contact us for supply of Potassium hydroxide Request Quote
